There are disk, network, and cluster systems out there that can deliver
400-600 MB/s aggregate IO to >=64 node runs. Talk to other centers and labs
and you will also hear about filesystems that are delivering 1-5 GB/s
across large numbers of nodes, depending on the network configurations.
I realize that your point was really that you wanted to see a whole system
where your 400-600 MB/s was delivered to _each_ node.
My point is that for n~=8 we are already there.
